MANHATTAN — Joan Rivers is reportedly in critical condition after being rushed to Mt. Sinai Hospital after an emergency call that she was in cardiac arrest, according to a law enforcement source.

The New York City Fire Department transported a woman matching the 81-year-old comedy icon's description to Mt. Sinai Hospital earlier this morning after receiving a call that the woman was in cardiac arrest at an Upper East Side clinic, Yorkville Endoscopy.

Rivers, 81, had been hard at work of late, co-hosting her E! TV show, "Fashion Police" and doing stand-up comedy. According to Ticketmaster, she had seven shows planned across the U.S. for November.

"Ignore aging: Comedy is the one place it doesn't matter. It matters in singing because the voice goes. It matters certainly in acting because you're no longer the sexpot. But in comedy, if you can tell a joke, they will gather around your deathbed," she wrote in the Hollywood Reporter in 2012. "If you're funny, you're funny. Isn't that wonderful?"
